Güroskoop

Güroskoop, also known as a gyroscope, is a device that measures or maintains orientation and angular velocity by exploiting the properties of angular momentum. It typically consists of a rotor spinning at high speed, mounted in gimbals so its axis can pivot freely in space. The spinning motion makes the axis resistant to changes in orientation, providing a reference direction.

Principle: A rapidly spinning rotor preserves its angular momentum. When external torques act on the gyroscope, the resulting motion tends to occur perpendicular to the applied torque, a phenomenon known as precession. This behavior allows the gyroscope to serve as a stable reference for measuring rotation or to stabilize objects by resisting unwanted changes in orientation.

Types and variations: Mechanical gyroscopes use a physical spinning wheel (or rotor) in a system of gimbals. Rate gyroscopes measure angular velocity directly, while optical and fiber-optic gyroscopes rely on light and the Sagnac effect to determine rotation without moving parts. Modern miniaturized versions include microelectromechanical systems (MEMS) gyroscopes, which are common in consumer electronics.

Applications: Güroskoops are used in inertial navigation and attitude control for aircraft, ships, and spacecraft, as well as in stabilization systems for cameras and drones. They play a key role in smartphones, wearables, and virtual-reality devices, where precise orientation sensing enhances user interaction and experience. In aviation and spaceflight, gyroscopes help determine orientation when external references are unavailable.

History: The concept emerged in the 19th century with demonstrations of rotational motion and angular momentum. The term gyroscope derives from Greek roots meaning circle-viewing. In the 20th century, practical gyroscopes were developed for navigation and control, notably contributing to inertial navigation systems and stabilization technologies.
